Species Information

Features include large yellow-green to yellow brown hairy to scaly cap, large white pores that tend to stain greenish, off-center to lateral stem, and growth on ground under conifers. Audet(1) supported the use of the name Scutiger ellisii. Albatrellus ellisii is found in ID, AL, AZ, CA, KY, NC, NJ, (Gilbertson), WA, OR, CO, WY, (Ginns); collections from BC are deposited at the University of British Columbia.
8-25cm or more, convex becoming flat, wavy or depressed, margin inrolled at first, often wavy; greenish to sulphur yellow or yellow-brown (often a mixture), sometimes with darker brown shades or stains when old; dry, "at first hairy or plushlike but the hairs often matted in age or grouping to form coarse scales", (Arora), a mixture of green, yellow, and lavender; dry, scaly, (Ginns), up to 17cm, circular to lobed or fan-shaped; yellowish green; coarsely scaly, scales finely tomentose, (Gilbertson)
thick, firm; "white, sometimes bruising greenish slowly" (Arora), "white when young, staining bluish lavender when cut, these stains in patches or some specimens staining green", (Ginns), up to 1cm thick, fleshy when fresh, drying hard and rigid; cream to pale tan, not zoned, (Gilbertson)
0.5-2 per mm, often decurrent; "white, usually staining greenish or yellow-green when bruised or becoming yellowish or dingy greenish in old age"; tube layer 0.2-0.6cm thick, (Arora), 1-2 per mm, circular to angular, walls thick becoming torn; cream, turning greenish when bruised, drying pallid or greenish; tube layer up to 0.3cm thick, cream to slightly greenish, (Gilbertson)
3-12cm or more long, 2-6cm wide, usually off-center or lateral, equal or wider at either end, solid, tough; usually colored like cap, (Arora), up to 8cm long and 5cm wide, central to lateral; greenish yellow; tomentose, (Gilbertson)
mild (Ginns)
spores 8-11(14) x 5-8 microns, elliptic to tear-drop-shaped (with prominent apiculus), smooth, inamyloid, colorless; basidia 4-spored, 40-48 x 8-10 microns, clavate, with basal clamp connection; cystidia or other hymenial elements absent; hyphae monomitic, generative hyphae with clamp connections, hyphae of context mostly 4-10 microns wide but some inflated to 20 microns, thin-walled to moderately thick-walled, with frequent branching and interwoven, weakly amyloid in scattered regions, gloeoplerous hyphae also present in context, these being sinuous and highly refractive in Melzer's reagent, hyphae of surface squamules more strongly amyloid, much distorted and fragmenting readily, irregularly inflated up to 30 microns, hyphae of trama mostly 2-4 microns wide, more uniform, more compactly interwoven, (Gilbertson), spores (8.0)8.6-9.6(10.0) x (5.6)6.0-6.8(7.2) microns, tear-drop shape to broadly elliptic, with prominent apiculus, smooth, inamyloid, colorless; paraphyses seen in one specimen, rare, 3.0-3.4 microns wide, filiform; cystidioles seen in two collections, infrequent, 10 microns wide, projecting to 30 microns, cylindric to fusoid, with thin colorless walls, (Ginns), spores 8-9 x 5-7 microns, elliptic, smooth, (Arora)
